Tiny little black ants  are common place throughout the world. Their name relates to their small size and their dark black color. They are usually only about 1/16th-1/8th of an inch. [spin]The Queen ants are about twice that size.

Little black ants  dwell underground in chambers hewed out of the earth. They are grouped in colonies, each containing a queen. The presence of a colony can be recognized by a tiny mound of fine dirt, seen above ground. They usually live at the edge of the forest or near human dwellings. Sometimes they are found in rotting tree stumps

Tiny black ant  colonies contain only one queen per colony. The queen breeds the worker ants who sustain the colony by foraging for food. After a colony has grown for several years, the Queen breeds a class of male and female swarmer ants. These are winged bearing insects. The swarmers engage in an autumnal mating ritual in which they fly through the air in search of a new colony. The male and female swarmers mate. The males die and the females tunnel under the earth to become the queen of a new colony.The queen lives underground without food until she has bred the new generation of worker ants who quickly go out and begin searching for food to sustain the colony. 

Little black ants  feed on sweet fruits, honey dew made by other insects and scraps of human food. Occasionally they will enter into homes in search of food. They are attracted to sweets and crumbs of food found in the kitchen.The little industrious ants are busy night and day foraging for food and they can carry up to 20 times their body weight in food back to the nest. That's the equivalent of humans carrying a 1,600 pound load! While adult ants have strong jaws, they imbibe food by sucking the juice out of the meal and leaving the dried residue.

When ants  enter into a house the best way to get them out is to set up ant bait stations, with ant poison. The ants will take the poison back to the colony, where they and the queen will ingest it and die. This technique takes several weeks to fully work, but is an effective form of ant eradication.
